Hydrogen sulfide-rich groundwater discharges from springs into Lower Kane Cave, Wyoming, where microbial mats dominated by filamentous morphotypes are found. The full-cycle rRNA approach, including 16S rRNA gene retrieval and fluorescence in situ hybridization (FISH), was used to identify these filaments. The majority of the obtained 16S rRNA gene clones from the mats were affiliated with the "...

A 2-yr study was conducted to confirm that managed pastures can provide Holstein steers adequate P to meet their daily requirement. Treatments offered were trace mineralized salt with or without additional P. In the first year, 80 Holstein steers (248 kg of BW) were assigned to 4 grazing groups. Treatments were trace mineralized salt only or a 67:33 mixture of trace mineralized salt and dicalci...

Fadiheh copper-gold prospect area in northwest of Torbat-e Heydariyeh in Khorasan Razavi Province is located in the central part of the Khaf-Kashmar-Bardaskan magmatic belt. This area includes outcrops of Eocene volcanic-pyroclastic units with felsicـintermediate nature. The lavas are andesite and latite, and pyroclastic units include rhyodacitic tuff, andesitic lithic tuff and ignimbrite. Intr...

All-solid-state batteries (ASSBs) using sulfide solid electrolytes with high room-temperature ionic conductivity are expected as promising next-generation batteries, which might solve the safety issues and enable utilization of lithium metal anode to further increase energy density cells. Most researchers in academic community currently focus on developing novel electrolytes, clarifying interfa...
